BATTERY CABLE AND POST CLAMP J ohn B. Batlle, Los Angeles, Calif.

Application April 29, 1948, SerialNo. 23,961i

2 Claims.

The present invention has to. do withv conductor cable terminals andconnectorsand has more specific reference to a novel and practicalclampfor connecting the conductor cable. to the post of a. conventionalstorage, battery.

More specifically, the invention 'appertainsto a structurepossessed ofsimplicity and features of refinement such as render the means, as awhole, more aptly fitted and satisfactory to serve the requirements ofmanufacturers and users.

All wh have had to attach and detach cable clamps are aware of thedifiiculties and distress encountered and it is the purpose of theinstant invention to provide a simple and economical clamp which iscomplete without being complex and is structurally designed to enable itto be attached and detached without requiring the use of special toolsand implements. 1

In carrying out the principles of the present invention I provide astorage battery post clamp or terminal which is characterized by foursimple parts, the post clamp, the cable terminal, the connecting boltbetween the clamp and terminal, and a handle equipped nut formaintaining the parts assembled and readily disconnectible if and whennecessary.

Stated somewhat more explicitly the invention is characterized by theaforementioned complemental parts, the clamp having a lug and theterminal having .9, lug, the two lugs being overlapped and keyedtogether and said lugs being bifurcated to expedite the step ofassembling and disassembling.

Other objects, features and advantages will become more readily apparentfrom the following description and the accompanyin illustrativedrawings.

In the drawings:

Figure 1 is a top plan view of the essential parts, the clamp andterminal with the bolt and nut means removed.

Figure 2 is a side elevational View of the complete assemblage, allparts being shown operatively connected, a portion of the terminal beingbroken away to uncover and show the bolt.

Figure 3 is an end view of Figure 2 observing same in the direction fromright to left.

Figure 4 is a perspective view of the clamp.

Figure 5 is a perspective view of the cable terminal inverted.

Referring now to the drawings by distinguishing reference numerals thepost clamp, as a unitary device, is denoted by the numeral 1 in Figure 4and comprises a single casting or equivalent structure including a splitcollar 8 which is adapted to embrace the battery post (not shown), saidcollar having outstanding prongs. B whichare apertured to. accommodate aclamping bolt (not shown)- One side of the collar is. flattened as atl0- and extending outwardly from this is 2. lug H which. is bifurcated,the furcations being denoted by the numerals I2. Incidentally, the upperpart or the. flat surface ill. provides an. abutment shoulder at. l3.

The complemental cable terminal unit is-denoted by the numeral I4-and isalso a single casting or equivalent body and includes a. Socket l5 toaccommodate thecable (not shown) and further includes a flattened endportion [6 and ail-outstanding lug H- .which overlapsandeorre sponds tothe lug H. The lug I1 is also bifurcated and the furcations are denotedby the numerals 8. The longitudinal edge portions of the furcationscarry reinforcing flanges [9 which straddle and abut the longitudinaledge portions of the lug ll. Thus, by providing flanges the lug I1 isformed with a keyway and the lug ll becomes a key and fits firmly intothe keyway. The tip ends of the furcations l8 rest firmly against theshoulder I 3. The flat surface It of the socket [5 provides a shoulderwhich rests firmly against the tip ends of the furcations l2. all asshown in Figure 2. The assembling bolt is denoted by the numeral 20 andpasses through the notches provided between the furcations and is heldin place by a ring nut 2| which is fitted on the threaded end and whichis provided with a suitable hand-grip 22. The nut means is denoted as aunit by the numeral 23.

In practice the socket equipped fitting or terminal I4 is secured to thecable (not shown). The split clamp or collar 8 is fitted over the bottompost (not shown) and bolted in place in the usual way. Then, therespective lugs II and I! are fitted together so that the coactingshoulders abut and so that said lugs are properly keyed and firmlyfitted together. No special tools are required since the nut means 23makes it possible to bind the lugs together or separate same whenevernecessary or desired.

Changes in shape, size, materials and rearrangement of details and partsmay be resorted to in actual practice, so long as they do not departfrom the spirit of the invention or the scope of the appended claims, asis well understood.

Having described the invention, what is claimed as new is:

1. A battery post clamp construction of the class described comprising asplit clamp adapted to embrace a. post, said clamp being provided midwayof its top and bottom surface with an outstanding bifurcated rectangularlug adapted to accommodate the passage of a clampin and assembling bolt,the outer peripheral surfaces above and below said lug being flattened,a cable terminal comprising a, socket attachable to the cable, saidsocket being provided with an outstanding lug, said lug being alsorectangular and superimposed upon the first named lug and beingbifurcated, the coacting bifurcated portions of the lugs beingoppositely directed and providing a passage for a, clamping andassembling bolt, a bolt passin through said passage, a nut on thethreaded end of said bolt, and a finger-piece attached to said nut, andthe tip ends of the furctions of said second lug being fiat and restingin firm contact with the coacting fiat surface on said clamp.

2. A battery post clamp of the class shown and described comprising asplit collar constituting a clamp and adapted to embrace a battery post,said collar having outstanding connectable prongs on one side, thediametrically opposite side being flattened and provided with anoutstanding rectangular bifurcated lug, said lug being situated midwaybetween the top and bottom surfaces of the collar, the outer tip ends ofsaid furcations bein flat, a cable terminal socket attachable to acable, said socket being provided on its anchorable side with a flatsurface providing abutment means for the flat tip ends of saidfurcations and being further provided on the same side with anoutstanding rectangular lug corresponding in length with the first namedlug, the free tip end of the furcations of the sec- 0nd lug firmlyabutting the adjacent fiat surface on said collar above said first namedlug, the second named lug having its under side grooved and defining akeyway and longitudinal keying ribs, the first named lug fitting intothe keyway and being confined in place by the complemental retentivekeying ribs, the coacting bifurcated portions of the lugs beingoppositely directed and providin a passage for a clamping and assemblingbolt, a bolt passing through said passage, a nut carried by thescrew-threaded end of said bolt, and a finger piece attached to saidnut.
